Overview

What this migration involves

Moving from MiniCRM to Nutshell is a record-model translation project first and a data-transfer project second. MiniCRM uses a card-based container (Karty) as its primary record, which can hold contact details, custom fields, and task associations simultaneously. Nutshell uses standard CRM objects — Contacts, Companies, and Opportunities — with explicit relationships between them. We split each MiniCRM Card into the appropriate Nutshell object during migration, preserving custom field values and card-level notes against the correct record. Automation rules (Automatyzacje) cannot be exported from MiniCRM's API and are documented for rebuild in Nutshell's workflow tools. Because MiniCRM is a Polish-market product, field labels, pipeline names, and any custom field names require scoping with the customer's team before mapping begins. We handle the data migration end-to-end; Nutshell's own Import2 integration handles supported sources natively, but for MiniCRM — which lacks a documented bulk export endpoint — a scripted approach using available integration endpoints and structured CSV exports is required.

MiniCRM

What's pushing teams away

  • Pricing structure is opaque and not clearly communicated — a G2 reviewer explicitly noted difficulty understanding what they were paying for and which features were included at their tier.
  • Limited advanced features as the team scales — power users outgrow the platform's capability ceiling for complex pipelines, custom objects, and integrations.
  • Recent acquisition by group.one introduces uncertainty — customers on review platforms express concern about product direction, support continuity, and whether pricing or terms may change.
  • Polish-language documentation and support — non-Polish speakers may find help resources and customer support limited when troubleshooting migration-related issues.
  • Lack of bulk API tooling — teams with large datasets report difficulty exporting data efficiently, making migration projects more manual and time-consuming.

Choosing

Nutshell

What's pulling them in

  • Lowest cost entry point among mid-market CRMs—Foundation plan starts at $13/user/month, making it accessible for teams validating CRM fit before committing.
  • Integrated sales automation and email sequencing on Pro plans without requiring a separate email marketing platform, per verified Capterra reviews.
  • Consistently praised for intuitive interface and fast onboarding, with case studies reporting 100% team adoption rates within initial deployment periods.
  • Strong customer support responsiveness cited across G2 reviews, with dedicated support tiers available on Enterprise plans.
  • Native integrations with WhatsApp, Facebook Messenger, Instagram, and Slack reduce reliance on third-party middleware for common communication channels.

Object mapping

How MiniCRM objects map to Nutshell

Each row shows how a MiniCRM object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

MiniCRM

Card (Karta)

maps to

Nutshell

Contact or Opportunity

1:many
Fully supported

MiniCRM Cards are the primary record container and can hold contact details, deal information, custom fields, notes, and tasks simultaneously. We split each Card into a Nutshell Contact (for person/company identity) and, where deal values or pipeline stages exist, a related Nutshell Opportunity. The split logic is driven by whether the Card has an associated Interest (deal) record. We preserve Card-level custom field values by mapping them to Contact custom fields or Opportunity custom fields depending on which entity the field logically belongs to. Any Card without contact details becomes a Company-only record in Nutshell.

MiniCRM

Contact (Kontakt)

maps to

Nutshell

Contact

1:1
Fully supported

MiniCRM Contact fields (name, email, phone, address) map directly to Nutshell Contact fields. We use email as the deduplication key during import. If a Contact in MiniCRM is associated with a Company (Firma), we resolve the AccountId by matching the company name or domain. Nutshell's Contact object does not have a separate Lifecycle Stage property, so any stage or status value from MiniCRM maps to a custom Contact field for reporting purposes.

MiniCRM

Company (Firma)

maps to

Nutshell

Account

1:1
Fully supported

MiniCRM Company records map to Nutshell Account. Company name becomes the Account name; available address and domain fields map to Account address fields. MiniCRM Company records may have fewer normalized fields than typical CRM Accounts, so we flag any empty fields during scoping and confirm with the customer's team whether those fields were intentionally left blank or reflect incomplete data. We create Accounts before Contact import so that the Account relationship is satisfied at the moment of Contact insert.

MiniCRM

Deal / Interest (Interes)

maps to

Nutshell

Opportunity

1:1
Fully supported

MiniCRM Interests (Interesy) map to Nutshell Opportunities. The Interest name becomes the Opportunity name; deal value maps to Opportunity amount; pipeline stage maps to Opportunity stage. We document each MiniCRM pipeline stage name during discovery and map it to the nearest Nutshell stage value (Prospecting, Qualification, Proposal, Negotiation, Closed Won, Closed Lost). If MiniCRM pipeline stages do not map cleanly, we configure custom stage values in Nutshell before migration. Closed dates from Interests migrate to Nutshell's close date field.

MiniCRM

Task (Zadanie)

maps to

Nutshell

Task

1:1
Fully supported

MiniCRM Tasks linked to Cards migrate to Nutshell Tasks linked to the equivalent Contact or Opportunity. We preserve due date, status, assignee (mapped via email to Nutshell User), and description. Task recurrence patterns from MiniCRM are not preserved; we document any recurring task rules as a separate section in the handoff inventory. Reminder settings in MiniCRM do not transfer and should be rebuilt as Nutshell Tasks with reminder flags.

MiniCRM

Note (Notatka)

maps to

Nutshell

Note

1:1
Fully supported

Free-text notes attached to MiniCRM Cards migrate to Nutshell Notes linked to the equivalent Contact, Account, or Opportunity. Note body transfers as plain text. Notes with Polish-language content retain the original text; we do not translate content. The association to the parent Card record is preserved by linking the Note to the corresponding Nutshell record during import.

MiniCRM

Custom Field (Pole dodatkowe)

maps to

Nutshell

Custom Field (Contact or Opportunity)

lossy
Fully supported

MiniCRM custom fields on Cards (text, number, date, choice types) are detected during scoping and mapped to Nutshell Contact custom fields or Opportunity custom fields based on whether the custom field applies to person/company identity or deal tracking. Choice fields require explicit value mapping — we document each MiniCRM picklist value and its Nutshell equivalent during scoping. Choice fields that cannot map cleanly to Nutshell's supported custom field types (text, number, date, checkbox, dropdown) are flagged as a configuration risk item.

MiniCRM

User / Worker (Pracownik)

maps to

Nutshell

User

1:1
Fully supported

MiniCRM Users (Pracownicy) map to Nutshell Users by email match. Name and role from MiniCRM transfer to Nutshell User fields. Role distinctions in MiniCRM may not map directly to Nutshell's permission model; we document the role mapping during scoping and flag any role that has no direct Nutshell equivalent. Users without a matching Nutshell User go to a reconciliation queue for the customer's admin to provision before record import resumes.

MiniCRM

Tag / Label

maps to

Nutshell

Tag

1:1
Fully supported

Tags applied to MiniCRM Cards for segmentation migrate to Nutshell Tags on the equivalent Contact, Account, or Opportunity. We deduplicate tags during import to avoid recreating a messy taxonomy in Nutshell. If the customer has a large tag volume (over 500 distinct tags), we recommend a tag consolidation step during scoping to reduce noise in the destination.

MiniCRM

Attachment (Zalacznik)

maps to

Nutshell

Attachment

1:1
Fully supported

File attachments stored against MiniCRM Cards can migrate where the platform exposes them via the integration endpoint or CSV export. We flag any attachment size limits during scoping. We map file references to Nutshell Attachments on the equivalent Contact, Account, or Opportunity record. If MiniCRM exposes attachment URLs rather than file content, we migrate the URL reference as a Note with a hyperlink rather than as a native Nutshell Attachment. Attachment metadata (filename, upload date, file size) is preserved where available.

MiniCRM

Automation Rule (Automatyzacja)

maps to

Nutshell

None

1:1
Fully supported

MiniCRM automation rules (trigger/action workflows tied to card status changes, field fills, and deadlines) do not export via the documented API or integration endpoints. We document every active automation rule during discovery — including trigger, conditions, actions, and any delay or follow-up steps — and deliver a written inventory with recommended Nutshell equivalents (PowerDialer sequences, Task rules, or manual workflow notes). This is a rebuild scope, not a transfer. We prioritize documenting revenue-impacting sequences (deal stage triggers, follow-up reminders) first.

Pair-specific challenges

  • MiniCRM automation rules have no export path

    MiniCRM's Automatyzacje are server-side trigger/action workflows that are not exposed through any documented export endpoint, integration API, or bulk data tool. We cannot migrate them programmatically. During scoping, we document every active automation rule the customer has configured — including trigger conditions, actions, delays, and assigned users — and deliver a written inventory sorted by revenue impact. The customer's team rebuilds them in Nutshell using PowerDialer for sales engagement sequences or manually configured Tasks and reminders. This is explicitly a rebuild step, not a transfer.

  • Card-to-record split requires explicit design before migration

    MiniCRM Cards (Karty) are unified containers that can hold contact details, company details, deal values, custom fields, notes, and tasks simultaneously. Nutshell uses separate Contact, Account, and Opportunity objects with explicit relational lookups. The card-to-record split must be designed during scoping — we determine which Card fields belong to a Contact, which belong to an Account, and which belong to an Opportunity based on the Card's data profile. Migrations that skip this design step risk creating orphaned records, duplicate contacts, or incomplete deal histories in Nutshell.

  • Polish-language labels require translation scoping with the customer team

    MiniCRM is a Polish-market product. Field labels, pipeline stage names, custom field names, automation rule descriptions, and note content are primarily in Polish. The minicrm.io/help/export/ endpoint returns a 302 redirect and documentation is not publicly accessible in English. During migration scoping, we work with the customer's team to confirm the meaning of Polish-language labels in the data export. This adds a small overhead to the mapping phase — we cannot reliably translate pipeline stages or custom field names without customer input. We flag any ambiguous labels as risk items in the scoping report.

  • MiniCRM has no documented bulk export endpoint or rate-limit spec

    The MiniCRM Integrations Manual documents REST and XML synchronization endpoints but does not specify rate limits, bulk export behavior, or a dedicated migration endpoint. The help/export page is non-functional (302 redirect). We work around this by using the integration PDF as a reference, by requesting structured CSV exports where the platform supports them, and by using available REST endpoints with conservative request pacing. If the customer has a large dataset (over 10,000 records), we flag bulk export capacity as a technical risk during scoping and plan for incremental pagination rather than a single bulk pull.

  • Custom field choice values require explicit value mapping

    MiniCRM choice-type custom fields (single-select or multi-select) store display labels in Polish and may use non-standard value strings. Nutshell's custom field picklists use a separate label-and-value pair model. We must map each MiniCRM choice value to a corresponding Nutshell picklist entry during scoping. If the customer has created many choice values without a consistent naming convention, we deduplicate and normalize them during the mapping phase to avoid creating a cluttered picklist in Nutshell. This is a manual mapping step that cannot be fully automated without customer confirmation of value intent.

Migration approach

Six steps for a successful MiniCRM to Nutshell data migration

  1. Discovery and export assessment

    We audit the source MiniCRM account: total Cards, Contacts, Companies, Interests, Tasks, Notes, custom fields, and automation rules. We assess the available export path — specifically whether the integration REST endpoint, XML sync, or CSV export covers the customer's full data volume. We confirm the customer's MiniCRM subscription tier and any seat or record-count limits during this phase. We also review the Polish-language labels in the data export with the customer's team to confirm field and pipeline name translations. The discovery output is a written scope with a migration path recommendation and a flag for any technical export risks.

  2. Card-to-record split design and Nutshell schema setup

    We design the record-model translation: each MiniCRM Card becomes one or more Nutshell records (Contact, Account, Opportunity) based on the data present in the Card. We set up the Nutshell destination schema including custom fields on Contact and Opportunity (created via Nutshell field settings on the relevant paid tier), pipeline stage values (mapped from MiniCRM Interests), and Nutshell User records for owner reconciliation. We configure the pipeline structure in Nutshell before any data is loaded so that deal stages are available at insert time.

  3. Owner and user reconciliation

    We extract every distinct MiniCRM Pracownik (Worker) referenced on Cards, Tasks, and Notes and match by email against the Nutshell destination's User list. Workers without a matching Nutshell User go to a reconciliation queue. The customer's Nutshell admin provisions any missing Users (active or inactive depending on whether the original MiniCRM user is still active). Migration cannot proceed past record loading until OwnerId references are satisfied because Nutshell Tasks and Opportunities require an owner.

  4. Sample migration and reconciliation

    We run a sample migration importing a representative subset of Cards (typically 50-200 records) into the Nutshell destination to validate the card-to-record split, custom field mapping, and attachment handling. The customer's team reviews the migrated sample in Nutshell and confirms field mapping accuracy. We correct any mapping errors before proceeding to full migration. This mirrors Nutshell's own Import2 approach of starting with a sample import to verify correctness before committing to the full dataset.

  5. Full production migration in dependency order

    We run production migration in record-dependency order: Accounts (from MiniCRM Companies), Contacts (with AccountId resolved), Opportunities (with AccountId and OwnerId resolved), Tasks (linked to Contact or Opportunity), Notes (linked to Contact, Account, or Opportunity), Attachments (where file content or URLs are available), and Tags (deduplicated and applied to Contact, Account, or Opportunity). Custom fields are mapped during each phase. Each phase emits a row-count reconciliation report before the next phase begins. Automation rules are not migrated; we deliver the automation rule inventory document at this stage for the customer's admin to begin rebuilding.

  6. Cutover, validation, and automation rebuild handoff

    We freeze writes to MiniCRM during cutover and run a final delta migration of any records modified during the migration window. We validate record counts against the MiniCRM source export and spot-check 25-50 records for data accuracy. We deliver the written automation rule inventory with trigger descriptions, conditions, actions, and recommended Nutshell equivalents. We do not rebuild MiniCRM automation rules in Nutshell inside the migration scope; that is a separate engagement or an internal admin task. We support a three-day hypercare window to resolve any reconciliation issues raised by the customer's team post-cutover.

Strengths

  • Card-based record model is easy for small teams to understand and use immediately.
  • Monthly subscription tiers scaled to micro and small business budgets, with no upfront installation cost.
  • Built-in automation triggers and actions cover common follow-up sequences without third-party tools.
  • Active Polish-language support community and documented features tailored to local SME workflows.
  • Responsive browser-based UI accessible on desktop and mobile without requiring desktop software.

Weaknesses

  • API documentation is sparse — no public rate limit spec, no bulk export endpoint clearly documented, limiting automated migration options.
  • Pricing transparency is a known friction point — customers report difficulty understanding what features map to which subscription tier.
  • Small product team and regional focus mean fewer third-party integrations compared to global CRM platforms.
  • Automation rules cannot be exported and must be manually rebuilt in the destination system.
  • Recent acquisition by group.one introduces potential for product instability, API changes, or shifting support terms.

Strengths

  • Simple, intuitive interface with minimal learning curve for sales teams new to CRM
  • Per-seat pricing is transparent and predictable, with annual billing reducing monthly cost
  • Full data export tool available for all account data including backups
  • Open JSON-RPC API allows programmatic access to all core objects
  • Native multichannel engagement (email, SMS, WhatsApp) without third-party add-ons for communication

Weaknesses

  • Reporting and analytics are considered weak, requiring manual Excel exports for detailed analysis
  • No bulk API endpoint—migration requires paginated API reads that must be rate-limited carefully
  • JSON-RPC API is less common than REST, requiring custom integration code compared to standard REST CRMs
  • Add-on costs (Forms, Nutshell IQ, Email Marketing) are per-company charges that stack on top of per-seat pricing
  • Feature restrictions on entry-level plans mean teams often need mid-tier to get basic automation

Most MiniCRM to Nutshell migrations land between three and five weeks for accounts under 10,000 Cards with standard fields and no complex custom field structures. Migrations over 10,000 records, multiple custom fields per card, active automation rule inventories, or Polish-language label translation scoping move to six to eight weeks. The card-to-record split design phase adds one to two weeks of scoping time that is included in the overall timeline.
